Standard PolyDrain – Interceptor-2552&2542 Precast Trench Drain 4" ID w Ductile Iron Frame and Grate Standard Specification

System ID#: PD 2552&2542

Trench drain shall be PolyDrain; manufactured by ABT, Inc., 259 Murdock Road, Troutman, NC - (800) 438-6057. www.abtdrains.com

System Components:

Precast Trench Drain - The precast trench shall be manufactured using polyester polymer concrete with the following material properties when tested:

Property ASTM Test Method Value Compressive Strength ASTM C579 17,000 psi Minimum Bending Strength ASTM C580 4,000 psi Minimum Tensile Strength ASTM C307 2,000 psi Minimum Moisture Absorption ASTM C140 0.2% Maximum Chemical Resistance ASTM C267 Pass Freeze/Thaw w/o weight loss ASTM C666 1,600 Number of Cycles Minimum Resistance to Fungi ASTM G21 Zero (0) Rating Mold Growth UL/ULC Listed- Flame Spread UL-723 Class A

The trench consisting of 39.19” (1 meter) or 19.56” (1/2 meter) channels with nominal 6” (155mm) outside width, 4 “ (100mm) inside width. Pre-sloped channels shall have a standard slope of 0.6% with radius bottom. Non-sloping channels must have written approval by engineer prior to installation. Channels shall have tongue and groove joints. Grate lock down slots shall have polyethylene vibration dampening inserts. All channels must have full length anchoring ribs for a positive mechanical lock with the surrounding concrete.

Sidewall Extensions – Sidewall extensions for channels may be used for hydraulic performance or to maintain the standard slope of 0.6% in greater trench run lengths. Sidewall extensions shall be composed of similar material and thickness as the channels and shall have tongue and groove joints.

Frame & Grate: #2552&2542: Uncoated ductile iron conforming to ASTM A-536 with a minimum of 0.27Ft2 /L Ft (.083m2/Lm) open area. Grates shall meet a minimum 620 psi proof load per AASHTO M-306 test modified by utilizing a 9” x 3” load plate. The frames shall have .25” dia. x 4” long (minimum) anchors at all corners of each frame. Frames shall be independent of the channels. When a combination of one-piece frame and grates, removable grates with frame, and/or pedestrian safe grates are used; the locations of the grates shall be shown on the plans. Removable grates shall be retained in their frame utilizing stainless steel, tamper resistant locking devices. The grate retaining device shall withstand, without maintenance, repetitive cyclic vertical loads of 500 lbs. The retainers shall also withstand a pullout resistance of 250 lb. per foot after completing a 1,000 hours ASTM B117 salt spray test. The grate retaining devices shall not obstruct hydraulic flow in the channel. All grates shall be bicycle safe. Frames and grates shall be made in U.S.A., and shall conform to the FHWA's "Buy America" policy 23 CFR 635.410(b) and Federal Acquisitions Regulations (FAR) 52.225 “Buy American Act”.

Submittals: A Certificate of Compliance in conformance with the provisions of these Standard Specifications shall be furnished to the Engineer. Grates shall be independently tested to AASHTO M-306.
